compile --strict should skip missing pseudo translations

[danielchabr]

Describe the bug
lingui compile --strict shouldn't fail with pseudo language missing translations

To Reproduce
Having pseudo locale enabled in config pseudoLocale: 'pseudo' run lingui compile --strict to compile messages catalogs. The command will fail even when all translations are available because pseudo lang is taken into account when checking for missing translations

Expected behavior
the --strict flag should compile succesfully when all translations are available even when I use pseudo locales for testing
